Looking for RV companion?

Hi. I'm new and this is my first post.

I'm seriously thinking about getting an RV in a couple years when I'm financially set. In the mean time, I was wondering if there is a forum or place on the web with classifieds for people looking for temporary RV companions to share expenses? I'm looking at this coming summer to do this. I would rather travel with someone rather than rent, as I think I could learn more.

Please someone point me in the right direction.

Thanks,
Rami
